Potassium Bicarbonate

In concentrations greater than 0. 5%, KHCO3 can have toxic effects on plants (potassium bicarbonate has widespread use in crops, especially for neutralizing acidic soil, and is also under consideration as an organic fungicide), although there is no evidence of human carcinogenicity, no adverse effects of overexposure, and an undetermined LD50. According to The US Food and Drug Administration (FDA), potassium bicarbonate is "generally recognized as safe". Potassium bicarbonate is a colorless, odorless, slightly basic, salty substance. Potassium bicarbonate is soluble in water, and is often found added to bottled water to affect taste; however, it is not soluble in alcohol. High Quality Content by WIKIPEDIA articles! Decomposition of the substance occurs between 100 °C and 120 °C into K2CO3 (potassium carbonate), H2O (water), and CO2 (carbon dioxide).

Potassium FerrocyanideAlthough it is insoluble in alcohol, a liter of water can dissolve just under three hundred grams of the crystals, and the solution can react with acid to release toxic hydrogen cyanide (HCN) gas. Lambert M. S. Книга по Требованию
